PUMP.

Specification of Letters Patent No. 23,485, dated April 5, 1859.

To @ZZ whom it may concern:

Be it known that Jol-1N K. ONEIL, of Kingston, in the county of Ulsterand State of New York, have invented certain new and useful Improvementsin Pumps; and I do hereby declare that the following is a full andexactdescription thereof, reference being had to the accompanyingdrawings, making part of this specification, Figure l being a sideelevation of the pump; Fig. 2, a central longitudinal vertical sectionthereof; Fig. 3, a plan of the bottom of the upper casting; Fig. 4, aplan of the top or counterpart of the lower casting with valvesattached; Fig. 5, a transverse vertical section of the pump in the planeindicated by the line as Figs. l, and 2; Fig. 6, a view in perspectiveof one of the pistons, the upper piston head thereof, being removed toshow the interior arrangement; Fig. 7, a diagram showing the position ofthe parts that support the pump at the bottom of the well.

Like letters designate corresponding parts in all the figures.

In the construction of the pump body, my object is to produce a pumpwhich can be furnished at a moderate cost, and which is, at the sametime, effective and simple, not liable to get out of order, and canreadily be taken apart for inspection or repair. To accomplish theseobjects, the pump body is made of two castings, A, and B, which arefitted together by means of bolts passing through holes a, a, (Figs. 3,and 4,) and held by nuts, suitable packing b, being placed between thecastings to make the joints tight. The castings are formed as follows:

The bottom casting B, has a mouth c, opening into the middle of a waterpassage C, which extends the whole length of the pump, to the ports ofthe induction valves, whereby many impurities are at first eX- cludedfrom the pump. A horizontal partition d, separates this passage from thewater passages D, D, above, the valve ports f, f, of the inductionvalves, being in the outer ends thereof. These water passages areseparated from each other by a transverse partition g; (Fig. 2,) andabove them is another partition V, with openings c', z', therein, whichallow a communication between the water pas sages and the pistoncylinders above; and valve ports 7c, 7c, for the eduction valves, alsoopen into the air-chamber.

The upper casting A, of the pump, consists of the cylinders E, E, of adouble piston pump, and air-chamber F, situated between them.

Half-ball valves L, L, are conveniently used for the inductionvalves,thereby economizing space, and, at the same time, securing all theadvantages of the spherical valve. They may be secured to small metallicspring-hinges s, s, which extend inward toward the center of the pump,and are secured to the under side of the partition V, thereby offering amore open and uninterrupted passage for the water around the valves, andpresenting less opportunity for the lodgment of obstructions. Ordinaryball valves M, M, may be used for the eduction or air-chamber valves,retained in place by wires t, t.

An elevating pipe G, extends from the bottom of the air-chamber, upward,to the top of the well, where it is suitably connected with the workingfixtures H, (Fig. 1,) of the pump. There is an aperture Z, (Figs. 1, and5,) near the bottom of the airchamber, provided with a valve I, for thepurpose of allowing the water to escape from the elevating pipe, whendesirable, so as to prevent stagnation or freezing in said pipe. Thisvalve is controlled by the following means It is situated within theair-chamber, as shown in Fig. 5, and is fastened to a stem m, whichpasses through a guide n, its outer end being attached to a vibratoryarm 0, pivoted at its lower end to the pump.

A connecting arm p, is secured to the top of the vibrator'y arm, by astiE-knee joint, s0 arranged as to prevent the two arms straighteningbeyond a certain extent, substantially as represented in Fig. 5; and tothe lower end of said connectlng arm, is pivoted a small rod Q, whichextends upward to the top of the well, and is secured to an eccentric K,or any equivalent device, for actuating it. By simply turning theeccentric so as to raise the rod g, the valve will be forced inward, asindicated by red lines in Fig. 5, and the water will escape from theair-chamber, and, by consequence, also from the elevating pipe. A smallcoiled spring r, or its equivalent, is used between the vibratory arm 0,and guide n, to keep the valve closed at all other times.

The pistons of the pump are actuated by two levers T, R, one vibratingin the operating ixtures H, at the top of the well, and the other on thepump at the bottom of the well. These levers are connected by rods S, S,as represented in Fig. l, so as to keep them in parallel positions. Verysmall rods may be used for this purpose, (mere wires in fact,) since thelower `lever is actuated by alternately drawing, instead of pushing,said rods. rIhe piston rods N, N, are jointed at their upper ends to thelever R, and also jointed at their lower ends, respectively, to thepistons O, O, (Fig.l 2.). The pistons O, O, are made to serve as theirown guides, and thereby allow the jointing of the piston rods thereto,by the following construction: Iiachpistonl has two piston-heads,provided with high raised rims w, fw, the inner `edges h, 7L, of whichfit closely, but not tightly, in the cylinder, as shown in the drawings.Around the rims, except at said edges h, h, considerable space isallowed for the reception of the packing y, and coiled springs a', z,which are located within the packing, and constantly' press itoutwardagainst the side of the cylinders, without adding much to the frictionof the pistons in the cylinders. The springs are placed on each side ofa central disk u, situatedA between the two piston heads, the edge ofwhich reaches outward to the packing y; and they are always kept inplace by the edgest, L, of the piston heads. The parts may be securedtogether by a screw on the upper piston head,'passing through central hoes in the disk and lower piston head, and held by a nut. vVhen thusarranged, with the edges h, h, resting against the side of the cylinder,and separated a considerable distance from each other, the piston can bemoved directly up and down without being liable to cant and bind in thecylinder, while the piston rods N, N, can incline in either directionwithout interfering with the free working of the pump. And this is thuseffected by a simple cheap and light construction.

This pump may be used either above or below the surface of the water;and a conyenient means of locating it securely, is represented inv Fig.7', whereit is fastened to cross-pieces U, U, the ends of which extendto the sides of the well.

I claiml. The combination and arrangement of the vibratory arms p, 0,rod g, stem m, guide 12., and spring r, for controlling the Valve I,from the top of the well, substantially as described.

2. I also claim constructing the pistons G, O, with raised rims w, w,and guiding edges L, 7L, upon the heads thereof, in combination with thepacking y, coiled springs a, e,

andcentral disk u, larranged in the manner and for the purposes hereinset forth.

In witness that the above is a true speciiication of my'improved pump, Ihereunto set my hand this day of October, 1858.

JOHN K. ONEIL.
